Apparatuses and methods for creating a constant DQS-DQ delay in a memory device are described. An example apparatus includes a first adjustable delay line configured to provide a delay corresponding to a loop delay of a data strobe signal pathway internal to a memory, a second adjustable delay line included in the internal data strobe signal pathway, and a timing control circuit coupled to the first and second adjustable delay lines and configured to adjust a delay of the second adjustable delay line responsive to output from the first adjustable delay line and the data strobe signal pathway. 本发明描述用于在存储器装置中创建恒定DQS-DQ延迟的设备及方法。实例设备包含：第一可调整延迟线，其经配置以提供对应于存储器内部的数据选通信号路径的环路延迟的延迟；第二可调整延迟线，其包含在内部数据选通信号路径中；及时序控制电路，其耦合到所述第一及第二可调整延迟线，并且经配置以响应于来自所述第一可调整延迟线及所述数据选通信号路径的输出来调整所述第二可调整延迟线的延迟。
